Replacing Bearings and Seals on Boat Trailer with Grease Zerk Spindles

Question

Question:

I am replaceing the bearings and seals on my boat trailer that is set up with the Accu Lube system. Question is, do I need to pre-pack the bearings before assembly, then fill in the remaining voids by greasing from the front zert, or is it OK to put all the grease in from the Zert?

The EZ Lube spindle style with the grease zerk is designed for maintaining your bearings and not for the initial grease of your bearings. The best way to pack your bearings with grease is to us the Powerbuilt Deluxe Bearing Packer # ALL647646. You want to stick with the same grease as you used or you want to clean your spindles and hubs if you are changing grease as some do not mix well.

I recommend the LubriMatic Mini Grease Gun with Marine Corrosion Control and Trailer Bearing Grease # 30-800 and # L54FR to install and maintain your system.

To pick out a replacement grease seal you will need to measure the diameter of the spindle where the grease seal rides with a digital or dial caliper and then need to measure the hub bore where the current seal rides. With those two dimensions we can…

Answer 4

Since it's a 6 lug bolt pattern you most likely need the seal part #GS-2125DL but you'll need to verify this by pulling off a hub and measuring the diameter of the spindle where the seal rides. If it's 2.125 this is the seal or if…

The #168233 Double Lip Grease Seal has an outside diameter of 2.332 inches and an inside diameter of 1.688 inches. This seal is not compatible with a AF2527E seal with a O.D 2.312, because, even though the O.D. id very close, the inner diameter of…

When using an EZ-Lube hub, such as hub/drum assembly #AKHD-545-2-EZ-2K, on an EZ-Lube spindle it is not necessary to also use Bearing Buddy bearing protectors. An EZ-Lube spindle, such as part #TRU44FR, has a grease zerk fitting to allow you to pump…

EZ Lube axles like the item #T3584F-EZ-8974 come from the factory with just a little bit of grease in the bearings. The first time you use the EZ Lube feature to fill the axle, it will take a lot of grease. You will probably use 3/4 to a full tube…

A 14 oz container like the part #L11390 would be more than enough to grease your hubs. For a grease gun you would want part #L30200. Here's how to grease everything upon initial installation. First, grease your bearings and spindle by hand or…

The 84545 hub on your Stratos Trail Trailer uses the standard bearing combination for a 3,500 lb axle just like the #84545UC1-EZ and #84545BX. This means the correct bearing kit is the Hub Bearing Kit for Lippert, Dexter, and Al-Ko Axles - 3,500 lb…

Answer 11

It sounds like you may be pumping too much grease into your hubs and that is causing the seal to fail and leak grease out of the hub. You may have blown the seal already, but if not I would recommend trying a smaller amount of grease in the hub and…

Answer 12

Are you backing your trailer into the water when the hubs are hot? Typically that's what causes water intrusion into trailer hubs that use oil seals. If the seal can keep oil in without leaks it would be waterproof so the hot hub theory is…
